“…Besides the intrinsic wettability of solids, several chemical methods have been proposed to alter the surface wettability, mainly relying on introducing functional groups with hydrophilic or hydrophobic properties. 24 For example, hydroxyl (−OH), 32 carboxyl (−COOH), 33 thiol (−SH), 34 and amino (−NH 2 ) 35 are typical hydrophilic groups, while alkyl (−C n H 2n+1 ), 36 perfluoroalkyl (−C n F 2n+1 ), 37 phenyl (−C 6 H 6 ), 38 and alkenyl (−CH�CH 2 ) 38 are hydrophobic. Thus, those methods that can change the surface functional groups have the potential to modulate the wettability of the solids, including plasma treatment, surface chemical grafting, and UV irradiation.…”

“…Chemical vapor deposition (CVD) and chemical liquid deposition (CLD) are mainstream strategies for functional grafting (Figure b). Modification molecules such as thiol- and amino-based silanes are mainly used for hydrophilic modification, while alkyl, vinyl, as well as perfluoro-based silanes are usually used for hydrophobic modification. , In a typical CVD process, the modification molecules and target substrates are placed in a vacuum environment and kept at 70–110 °C to accelerate the evaporation of the molecules and form a self-assembled monolayer on the substrate. For example, Li et al modified 1 H ,1 H ,2 H ,2 H -perfluorodecyltrimethoxysilane on the substrate with CVD at 80 °C for 2 h to obtain a hydrophobic surface.…”

Inkjet printing provides an efficient routine for distributing functional materials into locations with well-designed arrangements. As one of the most critical factors in determining the printing quality, the impacting and depositing behaviors of ink drops largely depend on the wettability of the target surface. In addition to printing on solids with intrinsic wettability, various ink-drop impact dynamics and deposition morphologies have been reported through modifying the surface wettability including both homogeneous and heterogeneous, which opens up possibilities for applications such as advanced optic/electric device fabrication and highly sensitive detection. In this Perspective, we summarize recent progress in the modification methods of solid surface wettability and their capability in modulating the ink-drop impacting and depositing dynamics. The challenges facing ink-drop regulation by chemical modification methodologies are also envisaged at the end of the Perspective.

“…For example, noble metal nanoparticles on substrates are often used as special nanomaterials, namely biosensors, catalysts, and amplifiers of electronic and optical signals. In the works of Taiwanese scientists, 3-aminopropylsilatrane ( 1 ) was employed for anchoring NPs on substrates [ 82 , 83 , 84 ] of NPs on the silicon surface (SiO 2 ) and a good linker for plasmon resonance sensors based on gold nanoparticles (AuNP). In addition, it was revealed that the surfaces treated with APS ( 1 ) exhibit antifouling properties.…”

3-Aminopropylsilatrane and Its Derivatives: A Variety of Applications

Silatranes arouse much research interest owing to their unique structure, unusual physical–chemical properties, and diverse biological activity. The application of some silatranes and their analogues has been discussed in several works. Meanwhile, a comprehensive review of the wide practical usage of silatranes is still absent in the literature. The ability of silatranes to mildly control hydrolysis allows them to form extremely stable and smooth siloxane monolayers almost on any surface. The high physiological activity of silatranes makes them prospective drug candidates. In the present review, based on the results of numerous previous studies, using the commercially available 3-aminopropylsilatrane and its hybrid derivatives, we have demonstrated the high potential of 1-organylsilatranes in various fields, including chemistry, biology, pharmaceuticals, medicine, agriculture, and industry. For example, these compounds can be employed as plant growth biostimulants, drugs, optical, catalytic, sorption, and special polymeric materials, as well as modern high-tech devices.

“…In this study, a newly emerging pentacoordinate silicon compound, called silatrane, was used to construct a dense and robust diffusion barrier for Cu/SiO 2 /Si heterojunctions. The molecular structures of silatranes are analogous to those of silanes except that the open-chained alkoxy groups are replaced by a tricyclic caged structure with a transannular N → Si dative bond. − Due to the high structural stability of tricyclic cages, the risk of hydrolysis-driven self-polymerization of silatranes in solution is greatly reduced. Hydrolysis and condensation of the silatrane molecules are initiated when they contact the hydroxy groups on the SiO 2 surface, which is referred to as “controlled silanization”. , The controlled silanization facilitates the formation of well-oriented and highly packed organosilicon thin films.…”

With the rapid development of emerging technologies such as artificial intelligence and high-frequency communications, advanced subnanometer chips with a high-performance computing ability have received worldwide attention. The success of subnanometer chips relies on ultrafine pitch integrated circuit (IC) manufacturing technology and "more than Moore" threedimensional (3D) IC packaging technology. Copper (Cu) is a key conducting material used to fabricate planar and through-silicon-via Cu/SiO 2 /Si heterojunctions in 3D IC packaging architectures. The construction of an ultrathin diffusion barrier with a high film uniformity and adhesion strength at various Cu/SiO 2 /Si heterojunctions is an imperative and challenging task. In this study, we demonstrate that a molecule-based nanolayer assembled from amine-terminated silatrane is a promising diffusion barrier for blocking active atomic diffusion of Cu to Si. The breakdown temperature at which Cu silicides are formed at heterojunctions is taken as an indicator of the efficacy of the molecule-based diffusion barriers. Due to their superior structural stabilities and intermolecular networking abilities, silatranes can assemble into denser and more organized molecular nanolayers than commercially available amine-terminated silanes. Benefiting from the well-organized network structure, the silatrane-based barrier increased the breakdown temperature to 500 °C, which was greater than those seen without a barrier (400 °C) or with silane-based (450 °C) barriers.
